Repeated or prolonged exposure to the substance can produce target organs damage. Section 4: First Aid Measures Eye Contact: Check for and remove any contact lenses. Do not use an eye ointment. Seek medical attention. p. 1

2 Skin Contact: No known effect on skin contact, rinse with water for a few minutes. Serious Skin Contact: Not available. Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate medical attention. Serious Inhalation: Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek medical attention. Ingestion: Do not induce vomiting. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek immediate medical attention. Serious Ingestion: Not available. Flammability of the Product: Flammable. Auto-Ignition Temperature: Not available. Flash Points: CLOSED CUP: -27 C (-16.6 F). Flammable Limits: LOWER: 1.5% Section 5: Fire and Explosion Data Products of Combustion: These products are carbon oxides (CO, CO2). Fire Hazards in Presence of Various Substances: Flammable in presence of open flames and sparks. Explosion Hazards in Presence of Various Substances: Risks of explosion of the product in presence of mechanical impact: Not available. Risks of explosion of the product in presence of static discharge: Not available. Fire Fighting Media and Instructions: Flammable liquid, insoluble in water. SMALL FIRE: Use DRY chemical powder. LARGE FIRE: Use water spray or fog. Cool containing vessels with water jet in order to prevent pressure build-up, autoignition or explosion. Special Remarks on Fire Hazards: Catches fire if exposed to air. Special Remarks on Explosion Hazards: Not available. Section 6: Accidental Release Measures Small Spill: Absorb with an inert material and put the spilled material in an appropriate waste disposal. Large Spill: Flammable liquid, insoluble in water. Keep away from heat. Keep away from sources of ignition. Stop leak if without risk. Absorb with DRY earth, sand or other non-combustible material. Do not get water inside container. Do not touch spilled material. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition sources. Call for assistance on disposal. Section 7: Handling and Storage Precautions: Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not breathe gas/ fumes/ vapour/spray. Avoid contact with eyes In case of insufficient ventilation, wear suitable respiratory equipment If you feel unwell, seek medical attention and show the label when possible. Storage: p. 2

3 Flammable materials should be stored in a separate safety storage cabinet or room. Keep away from heat. Keep away from sources of ignition. Keep container tightly closed. Keep in a cool, well-ventilated place. Ground all equipment containing material. A refrigerated room would be preferable for materials with a flash point lower than 37.8 C (100 F). Section 8: Exposure Controls/Personal Protection Engineering Controls: Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective threshold limit value. Ensure that eyewash stations and safety showers are proximal to the work-station location. Personal Protection: Splash goggles. Lab coat. Vapor respirator. Be sure to use an approved/certified respirator or equivalent. Personal Protection in Case of a Large Spill: Splash goggles. Full suit. Vapor respirator. Boots. Gloves.
